Some people absolutely want indentation to be one specific size for everybody and don't fully understand that what might look readable for them at 2 space-widths, would be more readable for some others at 4 space-widths. Tabs are accessibility. People use spaces for the same misguided reasons they use px font sizes in css. (Rant over. Yeah, this annoys me.)
